Title: Centre-feed roll
Inventor: KING TIM
IPC: A47K10/38
Filed: 1996-12-13
Abstract: A centre-feed roll (1) is disclosed which is formed from two webs (2, 3) each having lines of weakness (10) which allow the web to be separated into a plurality of sheets (8, 9, 11). The lines of weakness of one web are offset from those of the other such that in use the sheets can be dispensed singly from alternate webs. The lines of weakness (10) are manufactured to be as weak as possible such that the frictional force exerted by the aperture (7) may be minimised and the web will break as soon as the frictional force between the web (2, 3) and the aperture (7) is present across the perforations. The webs do not form a rope and the next sheet is presented for the next user to grasp easily. A base for use with a centre-feed roll is also disclosed. The base is provided with a rim extending around an aperture, the rim projecting into the centre of the roll in use. The web passes through the aperture from the inner surface of the roll.

Title: Pivotal latching mechanism with interengageable latch arm and catch in a sectionalizer assembly
Inventor: BACON MARC S
IPC: H01H31/28
Filed: 1998-08-25
Abstract: A sectionalizer assembly includes a mounting structure having upper and lower electrical contacts, a sectionalizer tube, an actuating member mounted to the tube and movable from a non-actuated to an actuated position, and a pivotal latching mechanism having a pivot member, latch arm and catch. The pivot member is mounted to the lower electrical contact and to a lower end of the tube for undergoing pivotal movement relative thereto between locking and releasing positions. The latch arm fixedly attached to the pivot member extends outwardly therefrom and undergoes pivotal movement therewith between the locking and releasing positions. The catch is carried on a lower end of the actuating member and undergoes movement therewith. The latch arm has an outer end fittable within a recess in the catch that is open at least at one side thereof. The latch arm outer end interengages the catch within the recess thereof when the actuating member is at the non-actuated position and the pivot member is at the locking position. Such interengagement tends to maintain the pivot member in the locking position. The latch arm outer end disengages the catch recess as the actuating member is moved from the non-actuated position to the actuated position and the pivot member is moved from the locking position to the releasing position. The movement of the catch with the actuating member from the non- actuated position to the actuated position causes the latch arm to pivotally move away from and disengage the catch, permitting an upper end of the tube to move from a closed to open position relative to the upper electrical contact.

Abstract: A self-biasing magnetostrictive element (10) for use in a magnetomechanical EAS marker is a strip of amorphous alloy material distributed throughout the bulk of the amorphous alloy strip. The crystalline particles (12) are magnetized to bias the amorphous alloy strip (14) to resonate in response to an interrogation signal. The crystalline particles (12) are formed by heat-treating the amorphous alloy strip (14) at a temperature above the Curie temperature of the amorphous alloy in the presence of a longitudinal magnetic field. The alloy strip (14) is then cross-field annealed at a temperature below the Curie temperature of the amorphous alloy to form a transverse anisotropy in the amorphous bulk of the alloy strip (14). A  preferred alloy composition includes iron, cobalt, niobium, copper, boron and silicon.
